Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.

ePiX creates mathematically accurate, publication-quality figures, plots, and animations. The input syntax is easy to learn, and the output is expressly designed for use with LaTeX. Complete documentation and dozens of sample files are included.

IT++ is a C++ library of mathematical, signal
processing, and communication classes and
functions. Its main use is in simulation of
communication systems or for performing research
in the area of communications. The kernel of the
library consists of generic vector and matrix
classes and lots of functions for vectors and
matrices. Such a kernel makes the IT++ library
similar to MATLAB or GNU Octave.

The Shared Scientific Toolbox is a library that facilitates development of efficient, modular, and robust scientific/distributed computing applications in Java. It features multidimensional arrays with extensive linear algebra and FFT support, an asynchronous, scalable networking layer, and advanced class loading, message passing, and statistics packages.

pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML.

RKWard aims to provide an easily extensible, easy
to use IDE/GUI for the R project. RKWard strives
to combine the power of the R language with the
(relative) ease of use of commercial statistical
packages. While RKWard is far from finished, it is
already useful as an IDE interface to the R
language.

SCaVis is an environment for scientific computation, data analysis, and data visualization designed for scientists, engineers, and students. The program can be used for function and data plotting in 2D and 3D, histograms, statistical analysis, and symbolic calculations using the Matlab/Octave high-level interpreted language.

Mavscript allows the user to do calculations in a text document. Plain text and OpenOffice Writer files (odt) are supported. The calculation is done by the algebra system Yacas or by the Java interpreter BeanShell.
